There are very few projects that I've seen for Ruby on Rails over the years. No one uses it in comparison to the other frameworks available. I'd love to see some ruby projects if any one knows of any available.

I think that Ruby still has a little ways to go before you'll start seeing amazing web applications coming from it. The best way would be to simply start working on it yourself. Ruby is a great language and it's very intuitive; I'd recommend everyone to learn it.
